Abstract
System for treating fabrics in rope form in a closed ring, wet or dry, includes the arrangement of at least a main device in the form of a sucking conveying element with a perforated surface through which sucking action is applied to suck the fabrics onto a part of the perforated surface, and at least one secondary device to draw the fabrics in rope form near to the main device, the arrangement simultaneously providing positive carriage of the fabrics, and any of the operations of opening the fabrics in rope form, unfolding them transversely to their advancement direction, interchanging the fluids of the process with the fabrics and extracting such fluids in a controllable degree from the fabrics.
Claims15
Apparatus for treatment of fabrics in rope form circulated in a closed ring through the apparatus comprising:
- a first device comprising,
- a driven, hollow, cylindrical roller rotatably mounted on a substantially horizontal axis,
- a perforated outer wall on said roller,
- suction means operatively connected with said roller for drawing air from outside said roller through the perforations therein into the hollow interior thereof, and
- restricting means in the hollow interior of said roller for restricting the area of said outer perforated wall connected to said suction means to a working suction area on a lower portion of said roller;
- and
- a positively driven second device mounted in a position relative to said first device for engagement with at least part of the outer surface of the fabric and for feeding the fabric to said working suction area of said first device so that a part of the fabric passing between said first and second devices engages in direct contact said working suction area of said roller and said suction draws said part of the fabric in direct contact with said working suction area transversely with respect to the direction of feed of the fabric, the remainder of the fabric falling by its own weight away from said first device thereby opening the fabric by increasing the cross-section of the fabric in at least said transverse direction.
